¹⁵ These six towns will be a place of refuge for Israelites and for foreigners residing among them, so that anyone who has killed another accidentally can flee there.

¹⁶ “‘If anyone strikes someone a fatal blow with an iron object, that person is a murderer; the murderer is to be put to death.^{(A) 17} Or if anyone is holding a stone and strikes someone a fatal blow with it, that person is a murderer; the murderer is to be put to death.
